To all whom 2'25 may concern Be it known that 1, CHARLES J. DUFFY, a citizen of the United States,-and resident of Yonkers, county of VVestchester, and State of New York, have invented an 1m p rovement in Mold -Guides ,for Artificial Teeth, of which the following is a specifica-z tion.

The object of my invention is to provide dentists with apractical guide means for selecting special mold forms of crowns, whereby they may have in convenientview a large variety ofdifi'erent mold forms from which to select the desired crowmas to shape and color, and also'be provided with means which will enable them toreturn to the fac- .tory or warerooms, a single tooth form to be matched when its companion crown has been removed for use. Heretofore guides ofthis character have-been made as detachable bars adapted to a case and eachbar providto form and color, and returned to the dentist. During this time the dentist is without the-remaining five forms and may be inconvenienced thereby; More specifically, my

object is to so construct the bars that the crowns are removable as pairs with portions of the bar and 1n the manner only a single crown and a portion of thebar is returned to the factory for filling out or matchlng with a new crown, the remaining four crowns bein'gpreserved intact in the guide case or cabinet.

My invention consists in the guide bar or ed with a plurality of independentjclamp ingv means, said frame supporting 'a p lurality of independentlydetachable crown carrying bar sections, each adapted to a socket portion and separate clamping means,

so that any section with its attached crowns may be separately removed without disturbin the remalningsections and their crowns.

1y invention also compr-ehends details of Specification of Letters IPatent.

perspective views showing one of my im proved tooth supporting frames removed and with a section of the bar also separated; and Fig. 4: is an elevation of one of the bar sections; i I l 2 are top and bottom bars and 6 the back boardof the case; 3 are the side bars there- Patented July 25, 1922.-

Application filed August 11, 1919. Serial No. 316,524.

of. lniaddition' tothe side bars 3 there are a plurality of parallel intermediate bars '5 extending between the top and'bottom bars 2 and secured to theback 6. The inner side faces ofthe sidebars 3 andl'both side faces of the bars '5, are provided/with notches or slots This case is quiteshallow and needsno lid. In the spaces; between the bars 3 and 5 andhetw'een'the adjacent bars 5 are detachably arranged the crown holding frames 7, shown more fully in Fig. 3. When these framesflflwith their attendant tooth carrying'b'arsections, are in position in the case, the end pins 10 of'the frames fit into the opposite slots toihold the'frames in parallel relation, permitting them to be detached or turned up to remove a crown. Normally, the crowns carried by a frame overlie the next frame to make the arrangement of the parts more compact and to more fully eX- pose the crowns tov1ew, all of which will be understood by reference to Fig. 2.

" Considering now thespecific construction ofthe crown moldingframes and their associated parts as shown in Fig. 3, 7 is a sheet metal socket frame hav ng a longitudinal" socket or groove 8, shoulder ends 9 and spring clamping means 12 in the form of tongues. The end portions: 9 are. each provided with a pin 10 for'positioning the frame inthe case as above explained. In Fig. 5, the end portions [9 which constitute the shoulders are at the ends of the frame 7 and inner end portions forming the pins 10 adjac'ent their union with frame 7, whereas inFig; 3, these shoulders are in clearly formed end plates 9. In either case, how;

ever, the shoulder portion 9 or 9, as the case may be, prevents the blocks 13 extending beyond the ends of the frame 7. 13 are three wooden bar sections of preferably rectangular form and are adapted to fit end to end and be received in the socket portions 8 of the frame 7, the respective sections 13 being clamped in position by one of the clamping tongues 12. In Fig. 3 is shown two of these bar sections 13 clamped in position in the frame 7 and the third section 13 detached for more convenient understanding of the capacity of these means. Each of thesections 13 is provided with two spring prongs or holders 14 over which the crowns 15 may be placed and detachably.

held by the spring prongs or holders ll entering the holes or recesses 11 in the crowns. The crowns have their numbers burned indelibly in the labial or buccal surfaces and these numbers determine the desired mold and shade, and corresponding designations are printed or. applied to the bar sections 13, some of these being indiconstituting a pair and these maybe at llICllGCl'ftO a single bar section and when one crown is removed for use, the section with the remaining crown is returned to the factory or wareroom of the manufacturers, to be matched with anew crown. In this way, the dentist is only missing temporarily one crown instead of atleast 5 crowns as heretofore has been the practice. It is manifest that I am not to be restricted to supporting the two similar right and left crowns on a single section 13, as they may be arranged in other ordersif so desired. Likewise, it will be understood, that while I have found three sections 13 for two crowns each best suitable to the purposes of the invention, the frame 7 may be. adapted to 2 or more of such sections, as may be desired.

It will now be apparent that I have devised a novel and useful construction which embodies the features of advantage enumerated as desirable, and whileI have in the present instance shown and described the preferred embodiment thereof which has been found in practicetogive satisfactory and reliable results, it is to be understood that I do not restrict myself to the details, as the same are susceptible of modification in various particulars without departing from the spirit or scope of the invention.

Having now described my invention what I claim as new and desire to secure by Let ters Patent is I do not confine myself to any 1. A mold guide for artificial teeth consisting of a case containing a plurality of detachable teeth supporting frames, .each comprising a metal frame having means for positioning it in the case and providlng a socket structure open throughout its length at one side and having clamping means, and a plurality of bar sections fitting end to end in abutting relation in the socket structure and detachably secured in place by the clamping means, said sections each having means for detachably holding a plurality of teeth, the construction being such that any section with its teeth may Toe-removed without disturbing the remaining sections.

:2. The invention according to claim 1,

wherein the detachable teeth supporting frames are hinged in parallel relation at a distance apart, so as to avoid direct contact but sufficiently close that the artificial teeth carried on the blocks of one supporting frame will overlap and rest upon the next adjacentv supporting frame, whereby said tened surfaces to insure stability and pro vide a surface for the tooth deslgnating indicia.

a. A supporting frame for a plurality of teeth and suitable for a mold guide for facilitating selection of teeth, consisting of a metal socket frame having pivoting means at each end and open on one side along its entire length, and also provided with spring clamping means at intervals along its length, combined with a plurality of detachable teeth'carrying bar sections arranged end to end in abutting relation and fitting the socket of the frame. said sections each separately removable without disturbing the remaining section or sections and each having means for detachably holding'a plurality of teeth in separated relation.

5. A cabinet for artificial teeth consisting of a case, combined with a plurality of detachable teeth supporting frames, each comprising a socket structure formed of sheet metal bent into U shaped form in cross section having a-wide seating lower portion and a series of spring tongues opposite to said supporting portion and having its ends provided with oppositely projecting pins adapted to fit in the case for holding the socket frames in parallel relation and permitting them to be oscillated, a plurality of substant1al1yrectangular blocks arranged end to eral rectangular. cross section presenting fiatend and fitting the socket frame and respectively clamped therein by the spring tongues, said blocks provided with a plurality of tooth supporting devicesffor detachably holding a plurality of artificial teeth to each block and permitting them to be separately removed, the construction being such that one or more of the blocks may be removed from each socket frame Without interfering With the operative relation of 10 the socket frame with the case.

In testimony of which inventionI hereunto set my hand.
